How an Electromagnetic Pulse Bomb Could Wipe Out America's Computers

Imagine that every electronic device in the United States is suddenly fried. For the most part, people have electronics to make their lives easier; a cell phone is easier than a land line, a computer is easier than looking through a book, and Wii sports is easier than real sports. The truth is that if terrorists detonated an electromagnetic pulse bomb 300 miles above the US, it could fry every electronic in the country.
The wave spreads and destroys all electronic circuitry so everything electronic would be crippled and no longer useful. The pulse of energy from this weapon creates a large magnetic field that is devastating to electronics but is considered non-lethal to humans.
